Bioshock’s little sisters: rescue or harvest? We show the best approach

Bioshock gives you a choice to either kill or rescue the little sisters, and …

Bioshockended up being quite the experience, but the game asks you one very large question: do you save or do you harvest the little sisters? The little girls who run around the game world collecting the mind- and body-altering ADAM give you a bonus either way: if you harvest them by killing the little girls, you get 160 ADAM. If you save them, you get 80 ADAM. However, the question is made more difficult by the fact that the more sisters you save, the more you're rewarded with ADAM and items by another character in the game. So which way gets you more ADAM?

One of our forum-goers, twinky, decided to find out. He graphed the difference between killing and saving the sisters in terms of the ADAM you receive, and he found that while at the beginning the bonus for killing is great, towards the middle and end of the game the bonus packages you receive for saving the little girls levels out most of the short-term gain.

While this decision does affect your ending, and whether you can sleep with yourself at night, if you're worried that by saving the little sisters you will be missing out on the ADAM needed to upgrade your powers, don't be. The game will take care of you either way.
